Quantum mechanics can describe a very small object’s behavior through a mathematical theory. The object can be 10,000,000,000 times smaller than the average human. Many theories and discoveries were made prior to quantum mechanics. Some include Newtonian Mechanics, Kinetic Theory, and the discovery of the electron. One reason Quantum Mechanics was discovered after many other things is because it is complicated. Quantum mechanics is difficult to understand, and a person must first understand the basic elements before trying to understand the more complicated areas. Matrix Mechanics was introduced by Werner Karl Heisenberg in 1925. Heisenberg’s Uncertainty Principle states, “The more precisely the position is determined, the less precisely the momentum is known in this instant, and vice versa.” Classical Mechanics has no limit to how accurate one can measure the position and momentum of a particle. But in Heisenberg’s Uncertainty Principle, this no longer applies. Taking the minimum uncertainty wave packet (in the form of a Gaussion) gives you the highest precision in measuring position and momentum. A classical particle and a Gaussion wave packet move basically the same way. As time increases, the packet spreads. The spread of the wave packet shows the uncertainty on the particle’s position.
